An exclamation mark after a number is the symbol for the factorial function.

It might be the symbol for the mathematical function "factorial". 5! would be 5X4X3X2X1.

10! and 6! means factorial of 10, and factorial of 6, respectively. You can calculate that on most scientific calculators - or you can multiply all numbers from 1 to 6 for the factorial of 6, and all numbers from 1 to 10 for the factorial of 10.

#include int main() { int fact,Factorial; printf("Please Enter Factorial Number\n"); scanf("%d",&fact); Factorial=func_fact(fact); printf("factorial is %d\n",Factorial); } int func_fact(int number) { int i; int factorial=1; for(i=number;i>=1;i--) { factorial=factorial*i; } return factorial; }

The exclamation point is the symbol for the factorial function. For integer values of n, n! = 1*2*3*...*n The factorial is critical for calculating numbers of permutations and combinations.

The value of 9 factorial plus 6 factorial is 363,600

It is 4060.

factorial of -1

The symbol commonly used to denote factorial is the exclamation point ( ! ). E.g. 1! = 1 2! = 2 3! = 6 4! = 24 5! = 120 x! = x*(x-1)*(x-2)*(x-3)*(x-4)* ... *3*2*1 , where x is an integer.

Factorial is a Mathematical Function.Factorial returns the product of all numbers from 1 to itselfe.g. Factorial 5 = 5*4*3*2*1 = 120It is expressed as n! = factorial of nTo implement it in Visual Basic, there are two methods-Function factorial(ByVal n as Integer) as IntegerIf n =< 1 Then factorial = 1:Exit Functionfactorial = n * factorial(n-1)End FunctionFunction factorial(ByVal n as Integer) as Integerfactorial = 1Dim a as IntegerFor a = 1 to nfactorial = factorial * aNext 'aEnd Function

It's math, math is always complicated. It's an ! because it is.

#!/bin/sh echo "Enter the number" read num factorial=1 for i in `seq 1 $num` do factorial=`expr $i \* $factorial` done echo $factorial

unsigned __int64 factorial(unsigned __int64 number) { unsigned __int64 factorial=1; while(number) factorial*=number--; return(factorial); }

As we know product of no numbers at all is 1 and for this reason factorial of zero =1and we know factorial of 1=1
